Technical Literature 6.1 Refer to the Appraisals listing on the BRANZ website for details of the current Technical Literature for Quickflash Ready-Made Flashings. The Technical Literature must be read in conjunction with this Appraisal. All aspects of design, use, installation and maintenance contained in the Technical Literature and within the scope of this Appraisal must be followed. Design Information General 7.1 Quickflash Ready-Made Flashings can be used as an alternative to the flashings specified within NZBC Acceptable Solution E2/AS Where a proprietary cladding manufacturer specifies a particular flashing system as part of their system, permission must be obtained from the cladding manufacturer before the flashing system is substituted with Quickflash Ready-Made Flashings. 7.3 Where Quickflash Ready-Made Flashings are used with other cladding systems not covered by the Appraisal (refer to Paragraph 2.1), designers must detail the junction between the Quickflash Ready-Made Flashings and the cladding to meet their own requirements and the performance requirements of the NZBC. Details not included within the Technical Literature have not been assessed and are outside the scope of this Appraisal. Durability 8.1 All materials used in the fabrication of Quickflash Ready-Made flashings are acceptable materials as set out in NZBC Acceptable Solution E2/AS1, Table Selection and use of the correct material for flashings in relation to Corrosion Zones B, C, D and E as specified in NZBC Acceptable Solution E2/AS1, Table 20 is the responsibility of building designers. Serviceable Life 8.3 Quickflash Ready-Made Flashings are expected to have a serviceable life equal to that of the cladding, provided the appropriate flashing material is selected and the flashings are maintained in accordance with this Appraisal. 8.4 On exposure to the environment, Quickflash Ready-Made Flashings may gradually lose their original surface finish. A faster reduction in appearance, and a reduction in serviceable life can be anticipated in severe industrial, geothermal, and marine exposures. Pg 3

4 Maintenance 9.1 Regular maintenance is essential for Quickflash Ready-Made Flashing installations to continue to meet the NZBC durability performance provision and to maximise their serviceable life. 9.2 Annual inspections must be made to ensure that all aspects of the cladding and flashing system, and any sealed joints remain in a weatherproof condition. Any damaged areas or areas showing signs of deterioration which would allow water ingress must be repaired immediately. 9.3 Regular cleaning (at least annually) of Quickflash Ready-Made Flashings is recommended to remove grime, dirt and organic growth and to maximise the life and appearance of the surface finish. Build-up of residue, mould or dirt can be removed by brushing with a soft brush, warm water and detergent. Abrasive cleaners, thinners, solvents or petrol must not be used to clean Quickflash Ready-Made Flashings. Painting may be considered necessary at some stage during the life of the flashings to restore appearance. Painting must be carried out in strict accordance with the instructions of the paint manufacturer for the painting of coated steel, stainless steel or aluminium.
